OLC - Expression used to display Activity Start time and End Time for Resource Alert

Summary: Can I please get some assistance with obtaining the correct variable code to use in my reminder alert for ILT activities? 

Content (required):

Version (include the version you are using, if applicable): I'm currently successfully using this code to give me the formatted Offering date: ${AlertUtils.formatDate(selectedCourseOfferings[0].offeringStartDate, 'dd MMM, yyyy')} = 10 Jun, 2022. What I need to add is code so that I can include the activity's Start and End time. I'd like to get the line in my alert to look like this:

10 Jun, 2022 from 1:00 PM to 2:00 PM

I tried using the following code snippets that I found in the "Upcoming ILT Activity to Instructors Reminder 1" Event Alert: ${activityStartDate} ${activityStartTime} ${activityTimezone} ${activityEndTime}
